Once BIP-444 activates, you’ll want to split your coins to protect against replay attacks.
1. Make a reorg transaction sending your coins back to yourself, including a large OP_RETURN. This TX will be valid only on the main chain and not the BIP-444 chain.
2. Once that settles, now you can create a second reorg TX, without OP_RETURN. This TX is valid only on the BIP-444 chain since it’d be a double-spend on main.
3. Now you can keep/spend your main chain #Bitcoin and your forked LukeCoin without replay risk.
Enjoy!
